Crux is a small UK brand that develops and manufactures products purely for mountaineering. They started out in 2002 with just 5 products: 4 backpacks and a tent. Since then the crux range has grown, and today includes sleeping bags, down jackets and hardshells.
Their ambition is to make great products, knowing that they are not for everyone, but that they are the right ones for a few. All of their gear is designed from personal experience. The factories, in the Far East and Europe, are small family affairs with whom Crux have worked for a long time.
